Problems solved by technology

The disadvantages are as follows: a. Multiple punctures are required in the abdominal wall, and the abdominal wall is supported by the body shaping device, which causes great damage to the abdominal wall and the exposure effect is not ideal
c. The operation is more troublesome

Embodiment 1

[0044] as attached figure 1 with figure 2As shown, a non-pneumoperitoneum suspension platform includes: a suspension part 2, a strut 3 and an in vitro suspension frame 4. The external suspension frame 4 is bent into a U shape by a stainless steel column, and the diameter of the steel column is 1 cm, which can suspend more than 30 kilograms of heavy objects. Suspension frame 4 in vitro is long 15cm, and bending part is the semicircle of diameter 12cm, and jack is arranged at the lower end. The suspension part 2 is a long rod with a length of 24 cm, and the section is a semicircular stainless steel column with a diameter of 1 cm, and the two ends are polished smoothly. The pole 3 is the same as the suspension part 2, and the middle 12cm of the two is connected by a rotating shaft 22, and the two can rotate around the axis to form figure 2 shown. The two ends of the strut 3 are respectively connected with the pull-in cable 15 and the pull-out cable 16, and the pull cable ex...

Embodiment 2

[0049] as attached Figure 4 with Figure 5 As shown, the gas abdomen-free suspension platform includes: a wire rope 11 , a suspension part 2 and a pole 3 . Steel wire rope 11 is that stainless steel wire is braided, and diameter 1mm can bear more than 100 kilograms. The suspension part 2 is a long rod with a length of 24 cm, and the section is a semicircular stainless steel column with a diameter of 1 cm, and the two ends are polished smoothly. The pole 3 is the same as the suspension part 2, and the middle 12cm of the two is connected by a rotating shaft 22, and the two can rotate around the axis to form figure 2 shown. A channel pipe 23 is arranged in the middle of the rotating shaft 22 for the wire rope 11 to pass through. The two ends of the strut 3 are respectively connected with the pull-in cable 15 and the pull-out cable 16, and the pull cable extends out of the body cavity to facilitate the operator to control the rotation of the strut 3 outside the body cavity. ...

Embodiment 3

[0053] Such as Image 6 , 7 , 8, this embodiment is similar to the second embodiment, the difference is that there is a through hole 27 on the suspension part 2, for the strut 3 to be inserted into the suspension platform during the operation. Steel wire rope 11 ends have holes, can insert pin 18 and do detachable connection. One end of each strut 3 is connected with an adduction cable 15 for easy retraction.

[0054] During the operation, first use two towel forceps to lift the abdominal wall 6, cut a small opening of 2-3 cm, expand the surgical incision, and insert the abdominal retractor, laparoscope and grasping forceps. Pull up the abdominal wall 6 with the abdominal retractor to form a certain intra-abdominal space, and under the laparoscope monitoring, vertically puncture the puncture needle with the wire rope 11 into the abdominal cavity from a suitable position outside the abdominal wall 6. Grab the puncture needle with the grasping forceps, pull it into the abdomi...

Abstract

The invention provides a pneumoperitoneum-free suspension platform. The suspension platform comprises a supporting rod and a suspension part which are arranged in a body cavity; a suspension device outside the body cavity extends into the body cavity and is connected with the suspension part to provide supporting force, the body cavity can be lifted upwards, and an operation space is formed. The suspension part is further connected with the supporting rod so as to further expand the operation space. According to the suspension platform, the advantages of a laparoscope and open operations can be achieved, and harm caused by carbon dioxide pneumoperitoneum can be avoided so that patients who have minimally invasive surgery indications but cannot resist general anesthesia and pneumoperitoneumrelated complications can also accept minimally invasive treatment, and indications of minimally invasive surgery are expanded.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gas abdomen-free suspension platform. Background technique [0002] With the progress of economy and society, patients have more and more urgent requirements for minimally invasive surgery, and most of the operations are completed by laparoscopy. Due to the secondary hypercapnia, air embolism, blood stasis and other complications of carbon dioxide pneumoperitoneum, its application in children with immature tissues and organs, pregnant women and elderly patients with underlying diseases is limited. Pneumoperitoneum-free laparoscopy uses external mechanical tension to provide operation space for surgery, does not rely on artificial pneumoperitoneum, reduces carbon dioxide pneumoperitoneum-related complications, and enables minimally invasive surgery indications but cannot tolerate general anesthesia and pneumoperitoneum-related complications Patients can also receive min...
